Injection rate shaping

Webb1 aug. 2024 · It has been found that injection rate-shaping allows to control the fuel flow from the injector at a variable needle height. A reduction of the linear range of the spray by 50% and a radial range by 40% compared to conventional settings within a specified time from the start of the injection was achieved. WebbInjection rate shape has a great influence on the spray evolution, and consequently on the performance and emission characteristics of compression ignition engines.

WebbIn general, theoretical studies have assumed that injection rate shape is perfectly rectangular, but in real cases, this is … With a square injection rate shape, the fuel injection rate increases very rapidly to a maximum (approximately constant) rate at the start of injection and decreases to zero very rapidly at the end of injection. This rate shape maximizes the amount of fuel injected in any given crank angle interval.
